The controller I put in has a small dial. I leave it all the way turned up and I have it tucked under the dash, just hanging there so I can reach it. I think when it is turned up all the way I might be getting a 10%~15% bump. That would be about 30+ HP and 50-60 in torque. I pull about 5 miles an hour faster up hills and my cruise control doesn't surge (speed up and down) so much to maintain a constant speed. You can turn the dial on and off, with the cruise control on, and notice the difference in smoothness and power. Unless you start modifying motor and messing with ECM, which would void warranty, you are not going to get much more power then this. Good luck
